I get you're mad at being pinned down, but please chill. I asked nicely MULTIPLE times.
Okay, this is something to work with. So, DNC's filler, in your mind, includes Cascade, Fountain, Reverse Cascade, Fountainfall, and Standard Step on CD.
Fair?
What these actions seem to have in common is that they're direct damage actions where two of them don't have preconditions (though Fountain can be used incorrectly), two of them do but the preconditions are light (they require a proc from one of the former two), and one of them has a CD, but it's a very short CD, less than 60 seconds (you didn't include Flourish, so I'm using "less than 60 seconds" as a working category here). Probably the better way to say that is 30 seconds (inclusive) or less?
So it would be fair to say things with a CD of greater than 60 or more seconds (so 59 or less is filler, 60 or more is not), which aren't always readily available, and which you want to use together and maximize by using within the party burst window(s), and your filler builds towards, would basically be non-filler?
So in the case of SMN, Primals, Gemshine, Aastral Flow, and Ruin 3 would be filler by this definition.
Demis, Searing Light, Enkindle, Astral Flow (for Baha/Phoenix), Energy Drain/Siphon, Fester/Painflare, and Ruin 4 would not be filler, nor would Ruin 3 while under Bahamut or Phoenix.
Again, it's not "fail states", so that's irrelevant. I'm looking at what are filler and non-filler actions in your example, and applying them fairly to SMN by looking at comparable abilities. (Granted, I'd rather you use literally any Job OTHER THAN DNC [or BLM] since DNC has the proc business going on, but...)
.
Can you give examples of any other Jobs?
Did you disagree with my RDM definition of Jolt/Thunder/Jolt/Aero (replace Jolt with Stone/Fire as procs available) are filler actions, for example?
I didn't ask for expertise.
I asked what you consider filler in other Jobs besides BLM. You don't need to be an expert to know how RDM works, for example. You CLEARLY don't for SMN, apparently.
You gave a definition there, "to maintain consistent timing of a jobs main rotation to avoid it drifting out of alignment"; pick ANY JOB IN THE GAME besides SMN or BLM and tell me which actions/abilities fit that definition.
